Application filed November 15, 1919. Serial No. 338,156.

I 'o (45.4 tU/tOJ/L- may concern: lie it known that I, Jo N 'i. THOMPSON, it the United States, and resident irt, in the county of Campbell and o. ntnchy, have invented new and iii Improi'enrents in Portable Signal De- Hces, or" which the following is a specification.

invention relates to portable signal .es, particularly to signal devices for i s-o in transmitting information or giving winnnmds in military or naval operations, 'as a burglar alarm or other alarm, for the or a acting the attention of the olice. o summoning help in cases of emergency, etc.

(fine oi? the objects or the invention is to provide ans whereby the gas pressure resulting ii" g of cartridges may be utilized siren c. a whistle, horiu lili him or air opernt all) which preferably produces the high shr Lil. note of a police whistle. Another object is to provide a chamber adapted to receive the explosion gases, or air forced thereiuto by the explosion and, ii i supply the gases or air to the siren. Another object is to provide means for but} -ing and storin the gases or air in a chamber vith which the whistle is connected, whereby a substantially continuous, prolonged tone may be obtained. Another object is to provide a safety means for relieving the pressure in the gas or air chamber in the event the pressure becomes excessive. Another obiect is to provide means whereby the siren may be operated by either the rearward or the forward movement of the bolt of the firing mechanism. Another object is to provide a visual signal adapted to be operated in conjunction with the aural signal.

The invention comprises the combination or a gun, whether manual, semi-automatic or full automatic, and of any type, together with a suitable signal. arranged to be operated by gas pressure produced by the gun, that is, by the explosive gases or bycompressed air or the like produced by the eio plosions. The preferred signal is a siren but in the broader aspect oi the invention the signal may comprise any suitable visual or aural or other device adapted to be operated by gas pressure. liioreover, the signal is preferably operated directly by the explosion gases but it may be operated indi- Figure 1 is a side view, partly in section of one type of signal device embodying my invention;

Fig. 15 is an 'elevationof an embodiment employing firing means, similar to that employed in the ordinary revolver.

In the'drawings is shown a pistol of the automatic type'having a grip G and a de tachalble or clip-loader magazine Mit'or holding cartridges 6 connected to a receiver R as is usual in pistols ofthis type. In the receiver R is bolt 1 adapted to move freely in a bolt chambe 2- and having inserted therein a movable firing pin 3. 'A spiral spring -41 mounted on a stud 5 at the inner end of the bolt chamber 2 has its free end engaging the rear end of the bolt 1 and is adapted to force by its expansion the bolt 1 forward after compression incident to the recoil of the bolt 1. An actuator b attached to the boit 1 extends upwardly through a longitudinal slot 7 in the upper section on line 14. "14: of

will of the receiver R and is adapted to be 1 the barrel 12, when the firing pin 3 is thrown forward by its inertia and the cartridge exploded, aid thus initial tiring is accomplished, after which the firing is renc ered automatic by the recoil of the bolt 1 against the spiral spring i and its subsequent expansion. The bolt 1 is provided with a cartridge extractor 8 and a cartridge ejector 9 operating in a longitudinal slot 10 in one side of the bolt 1, whereby the car'- tridges C are extracted and ejected automatically. The magazine M is provided with a spiral spring 11 adapted to push upwardly in succession into the receiver R the cartridges C as they are fired and tracted from the barrel 12.

Mounted in a threaded opening;- 13 in t barrel i2 is a siren 1%.

Obviously t ese features may be e =1- ployedin other GI..iOQllEl";G11l'S of? the 1 tion in view oi these examples.

One of the most satisfactory forms of invention is illustrated in Fig. 9 wherein tar hard is enlarged to erm a gas chaaihe' and the siren is mounted in the mouth or the barrel or chamber. The charibrr he be niade large e rough to store a consider quantity of and strong enough stand the inaxnnuin pressure of the J the siren niaj be mounted the mouth of Luv in the barrel in other embodin'icnts of the vention as shown by Fig. 9.

At the inner endof the air chamber is an opening e8 leading into an air storage chamber e9 in the grip G. at the upper end of the air storage chamber and above the opening 4:8 is located a whistle 14, while seated in the opening L8 is valve comprising a threaded nut 51 inserted in a threaded opening in the outer wall oi the air storage chamber e9, and having an axial opening 52 into which is inserted the valve stem A spiral spring -5-1l incloses the valve stem 53 and is adapted to normally hold the valve in its closed position. lln this form of my invention the piston i5 is adapted to be pushed inwardly by the rearward or recoil movement of the bolt 1, thereby forcing air to open the valve 50 and through the opening 48 into the air storage chamber 44, and consequently to operate the whistle ll. operation is repeated on each recoil of the bolt 1, the valve 50 alternately opening and closing and the surplus air being accumulated in the air storage chamber 49, so that thereby a substantially continuous, prolonged tone will be produced by the whistle in Fig. 11.

In the form shown in Fig. 13, an air chamber is mounted above the barrel 1? and has operating therein a piston 56, which is provided with a leather cup or other suitable packing L and with a rod 5'? connected at its inner end to an arm 58 operating in a slot 59 in the upper wallo-f the receiver R. The arm 58 is attached to the bolt 1, in which is a movable firing pin 60 having a spindle 61 extending rearwardly, which is inolosed by a spiral s ring 62 resting against a plug 63 and the rear end of the firing pin 60, the spring 62- being adapted to :torce forward by its expansion the firing pin 60 just previous to the initial firing. A spiral spring 64L engaging the bolt 1 and a stud 65 in the rear of the receiver ll forces forward the bolt 1 by its expansion after compression incident to the recoil of the bolt 1. An actuator arm 66 extends upwardly from the firing pin 60 through a slot- 67 in the fir ing pin 60 and the slot in thereceiver B and engages a spring detent 68 mounted on the upper wall of the receiver R. freeing which from engagement with the actuator arm 66 the firing pin 60 is forced forward by the spring and initial firing is accoirplished after which the firing pin 60 is held forward in fixed position by the spring 62 during succeeding firing oi the pistol, until the detent 68 again engages the actuator arm 66 and the firing pin 60 is again locked in position for initial firing as shown in Fig. 18. The detent 68 is provided with a lat- The valve 50 then closes and the era-l finger Fig. 1e) 3 means of which the detent may be lifted by the finger or thumb. fit the outer end of the air chamber 55 is an opening 69, in which is inserted a whistle i l. which is operated when the piston 56 is pushed it'orwzufd by the "forward movement of the bolt 1, thereby forcing air through the opening 69 and the wh tle As illi trated in Fi 15 the invention is not limited to devices automatic or semi-automatic firing n1 ism but may also be embodied in man devices. llhe device shown in. Fig. 15 c1 rises the doubleacting revolver type provided with a grip G arevolving magazine m, an enlar ed barrel l9 and siren let the barrel and siren being as'tliown in Fig. 9. While the device must be actuated me lly it possesses the advant e that the filing chaml: r ren'iains closed r and thereby pr vents the gases from escaping rearwardly more eitectuallv tl'ian in the case oi? automatic guns. By employing liri cans in which the firinp'chamber is or and in which the breech re 'r; .lO( ai'teriiring the may be c tircly prevented tfrom escar g the rear. thereby where liloreov. I the firing chamber rem ins sealed indefinitely after tiring, as for e ample in a single shot pistol, may be a to operate the s oomph, hausted before op k a fresh cartridge. l'lowe derstood that a check-valve may be used be tween the firing chamber and siren in any embodiment of the invention. It is also to be understood that any suitable breech closing mechanisnn firing mechanism, magazine, etc., may be employed.

From the foregoing it will be noted that the operation of the whistle i l in all forms o1": my invention is either directly or indirectly under the control of or incident to the firing of the gun, while the light 36 is under manual control and may be operated continuously or intermittently and in conjunction with the operation 0?: the whistle, as may be desired.
